when I try to convert this Hex: 780000465257A7054F5180E46C000100004652
to a decimal number, it should give me this decimal value: 2676089517297180626710225817179225498977322578
,
you can try that using this website: Hexadecimal to Decimal
but in PHP I use this code to convert the same hex to decimal:
echo hexdec("780000465257A7054F5180E46C000100004652");
the problem is, it gives me this value: 2.6760895172972E+45
this is not the right value at all.
what is the problem and how to solve it ?
